Troubleshooting Cadence Signal Reception

If your Polar cadence sensor is not working as it should, try troubleshooting before contacting your closest Polar Service.

CS cadence sensor W.I.N.D.
1. Have you taught the sensor to the training computer? See how to do this with CS500, CS600X / CS600, RCX5 or with RS800CX.
2. Does a light flash in the sensor when the cadence magnet passes it? The light indicates that the cadence sensor is positioned correctly and that the sensor is alive. For more on positioning, see CS cadence sensor W.I.N.D. user manual or installation video.

S-series cadence sensor
1. Is the sensor installed according to instructions? See User manual for S-series cadence sensor.
2) Does a light flash in the sensor when the cadence magnet passes it? The light indicates that the cadence sensor is positioned correctly and that the sensor is alive.
3) Does your bicycle have carbon fibre frame / handlebar / stem? This may reduce transmission range. Try reducing distance between training computer and sensor or try adjusting the transmission range.
4) Are you getting consistent zero readings? You may have exceeded 1500 riding hours and the battery of the speed sensor needs to be replaced. For battery replacement, please contact your local Polar Service here. S series cadence sensor transmission range is max. 80 cm/31 in. Recommended distance between training computer and sensor is 60 - 80 cm/23 -31 in.
